Description

Technical Field

[0001] This utility model belongs to the field of product testing technology, and in particular relates to a high-precision 3D / AOI rapid testing device. Background Technology

[0002] With the continuous development of the manufacturing industry, especially the advancement of the electronics manufacturing sector, the requirements for product quality control are increasing. In the production process, efficient and accurate inspection of the appearance and internal structure of electronic products, PCB boards, etc., has become a key link in ensuring product quality. Traditional inspection methods mainly rely on manual visual inspection or simple optical inspection instruments. These methods have drawbacks such as low efficiency, strong subjectivity, and easy omissions, making them difficult to meet the needs of high-speed, high-volume production lines. In recent years, with the development of computer vision and automation technologies, 3D automated optical inspection technology has gradually become mainstream. 3D / AOI technology utilizes high-resolution cameras with specific light sources to perform three-dimensional imaging of the object under test from multiple angles. Through software algorithms analyzing the image data, it achieves accurate identification of product appearance defects (such as poor solder joints, missing components, etc.) and internal structural problems (such as cracks, holes, etc.).

[0003] However, existing 3D / AOI inspection devices still have some shortcomings in practical applications. For example, the inspection accuracy of some devices is greatly affected by the stability of the light source, and changes in the external ambient light can easily lead to fluctuations in the inspection results. In addition, some devices have low levels of automation and are complex to operate, making them unsuitable for integration into large-scale production lines. To address these issues, we provide a high-precision 3D / AOI rapid inspection device. Utility Model Content
